They’re soft, chewy, and loaded with chocolate! Plus they’re massive and who doesn’t like huge cookies?! How to make these cookies Combine the butter, brown sugar, and white sugar Cream the ingredients together; either in a stand mixer or with hand mixers. Take your time here, we want the dough to be very creamy and smooth. Add in 2 large egg yolks and the vanilla extract and mix to combine. Use the extra egg white in this easy egg wrap recipe. Combine the egg white with cream of tartar (Here’s a description of what cream of tartar does in baked goods) Beat until light and fluffy Add the egg mixture to the wet ingredients and fold to combine Combine all the dry ingredients and stir to combine Add dry ingredients to wet ingredients Mix until you’ve got a thick smooth dough. Avoid over-mixing the dough; stir until everything is just combined. Add in the regular sized and miniature chocolate chips Instructions continued Stir to evenly disperse the chocolate Use a 1/4 cup measuring cup to measure the balls of dough Roll into flat wide discs and press M&Ms on top. Bake! Add a few more chocolate chips and/or M&Ms on top Chocolate chip M&M cookies baking tips Accurately measure flour: if a measuring cup is pushed into a bag or container of flour, it will pack in way more flour than is needed. To properly measure your flour, spoon the flour into the measuring cup until its overfilled. Then use the back of a butter knife to level the measuring cup at the top. (Video visual here) Room temperature eggs and butter: don’t melt the butter or the cookie dough will need to be chilled before baking. Check out this guide to bringing eggs and butter quickly to room temperature. Use quality ingredients: grab real butter (not margarine), pure vanilla extract, and high quality chocolate-chips (I recommend Guittard or Ghirardelli) for the best possible flavor. Use a 1/4 cup measuring cup: to get even and consistent cookie dough sizes. This will ensure even baking. More cookie recipes: Pumpkin Chocolate Chip Cookies reader favorite recipe!

Course Dessert Cuisine American Keyword Chocolate Chip M&M Cookies Prep Time 30 minutes Cook Time 12 minutes Total Time 42 minutes Servings 16 large cookies Ingredients3/4 cup unsalted butter, at room temperature3/4 cup (133g) brown sugar1/4 cup + 2 tablespoons white sugar2 large eggs1/2 teaspoon cream of tartar2 teaspoons vanilla extract1/4 teaspoon salt1 teaspoon baking soda2 and 1/4 cups (283g) all-purpose flour (See Note 1)2 tablespoons oat flour (oats that have been blended)1 and 1/2 cups (270g) chocolate chips1/2 cup (85g) miniature chocolate chips or chocolate chunks1/2 cup M&M's InstructionsPREP: Preheat the oven to 350 degrees F. Line a large sheet pan with parchment paper or a silpat liner and set aside.BUTTER AND SUGARS: In a large bowl, beat together the butter, brown sugar, and white sugar until light and creamy, about 3-4 minutes.EGGS: separate the eggs yolks from egg whites (discard ONE of the egg whites or save it for a different recipe). Beat the egg yolks and vanilla extract into the sugar and butter mixture. Place the remaining egg white in another bowl. Add the cream of tartar in with the single egg white and beat for several minutes until light and fluffy. Add the egg yolk mixture to the rest of the wet ingredients and mix until combined.DRY INGREDIENTS: in another bowl, mix together the salt, baking soda, flour, and oat flour (Measure the oat flour AFTER grinding and not before). Stir until combined.COMBINE: combine the dry and wet ingredients and stir until just combined. Stir in the regular chocolate chips, and the miniature chocolate chips or chocolate chunks. COOKIE DOUGH BALLS: Use a 1/4 cup measuring cup to measure out the dough onto a cookie sheet. Strategically place extra chocolate-chips and the M&M's on the tops of the cookies. (I don't mix the M&M's into the dough, but rather place them on the tops to get a pretty bakery-style appearance). Roll into big dough balls even in width and height. Place no more than 4 cookies per sheet pan.BAKE: bake in a fully preheated oven for 10-12 minutes or until the sides are lightly browned. Remove and allow to "cook" more on the cookie sheet for about 4-5 minutes before transferring to a cooling rack.Under-baking your cookies is key to soft and chewy cookies. These cookies have a very soft and chewy center with crisp edges.
